List strand edges touching a component on either side, projected from the edge lifecycle event log. Each active edge is evaluated against both endpoint components' latest scans: connected when both payload addresses resolve in their roll-ups, pending when a side's scan carries no strands, dangling when a resolved side no longer exposes the address, deleted when the latest lifecycle event is a deletion. ## OpenAPI ````yaml /api-reference/bundled.yaml get /v0/experimental/component/{id}/discriminator_edges openapi: 3.1.0 info: title: Gable API description: > API to interact with the Gable platform ## Authorization All API requests require an API key to be passed in the `X-API-KEY` header.

Ancestors are ordered root-to-immediate-parent: a `field_mapping` carries its `payload`, and a `payload` carries none. The chain's depth and each level's coordinate dimensions are the discriminator config's, not this API's — copy an ancestor's coordinates verbatim rather than rebuilding them.

Keys are the discriminator config's group_by dimensions for the group's level, verbatim; the dimension vocabulary is defined by the config, not by this API. Values are the exact grouping facts; null is the engine's null coordinate (fact unknown). Edges and BYO metadata attach to lineage by these coordinates, never by group ID (group IDs are derived from coordinates by the discriminator engine and are only stable within one discriminator config). additionalProperties: description: >- A grouping fact.
